Major change:
I no longer user HTML::Pager, SWISH and SWISH::Fork modules,
but SWISH::API (new interface to swish 2.4.x, which is required) and own
implementation of pager.
That saves round-trips of all results from swish-e to memory and to
HTML::Pager so this produces also significant speedup when result set is
large (tipically if you entered just a letter or two with huge number of
records).
